摘要: 目的 探讨术中应用紫杉醇与苏拉明对兔小梁切除术后抗增生作用的差异。设计 实验研究。研究对象 新西兰白兔24只。 方法 24只兔随机分为三组,每组8只(16眼),双眼均行常规小梁切除术。术中分别于巩膜瓣下应用0.3 mg/ml丝裂霉素C(对照组)、0.4 mg/ml 紫杉醇(紫杉醇组)、0.4 mg/ml苏拉明(苏拉明组)海绵片2分钟,并于术后第3、7、15、30天观察眼压及滤过泡形态并行滤过泡处结膜及周围角巩膜缘组织HE 染色和增生细胞核抗原(PCNA)染色。主要指标 眼压、滤过泡形态、组织病理染色。结果 术后15、30天,紫杉醇组功能性滤过泡比率较对照组高,苏拉明组功能性滤过泡比率较对照组和紫杉醇组均高(P均<0.05);术后第7、15、30天,紫杉醇组和苏拉明组的眼压均低于对照组(P均<0.05),苏拉明组的眼压低于紫杉醇组(P均<0.05);术后7、15、30天,PCNA 染色阳性细胞计数紫杉醇组和苏拉明组均低于对照组(P均<0.05),苏拉明组低于紫杉醇组(P均<0.05)。结论 紫杉醇与苏拉明辅助用于兔小梁切除术时,有助于维持功能性滤过泡。0.4 mg/ml 紫杉醇与苏拉明的抗增生能力优于0.3 mg/ml 丝裂霉素C,且副作用小。苏拉明的抗增生能力优于紫杉醇。

Abstract:  Objective To investigate the difference of short-term antiproliferative effect between taxol and suramin on trabeculetomy in rabbit. Design Experimental study. Participants 24 New Zealand albino rabbits. Methods 24 albino rabbits were randomly divided into three groups, each group consisting of 8 rabbits (16 eyes). Both eyes of rabbits were performed trabaculetomy and placed a piece of cotton with 0.3 mg/ml mitomycin C (MMC) for 2 minutes in standard control group, 0.4 mg/ml taxol for 2 minutes in taxol group, 0.4 mg/ml suramin for 2 minutes in suramin group respectively during the surgery. The filtration bleb and intraocular pressure(IOP) were observed at 3, 7, 15, and 30 days after surgery. Some conjunctival specimen were observed with hitochemicall (HE staining) and immunohistochemicall (PCNA staining) methods. Main Outcome Measures IOP, filtering bleb appearance, histopathological staining. Results The percentages of the functional blebs in taxol group and suramin group were higher than those in the control group (all P<0.05), and the percentage of the functional blebs in suramin group was higher than that in taxol group at 15 and 30 days after surgery (all P<0.05). IOPs in taxol group and suramin group were lower than that in standard control group (all P<0.05), and IOP in suramin group was lower than that in taxol group at 7, 15, 30 days after surgery (all P<0.05). PCNA staining showed the numbers of positive cell nuclear in taxol group and suramin group were lower than that in standard control group (all P<0.05), and the number of PCNA staining positive cells in suramin group had been lower than that in taxol group at 7, 15, 30 days after surgery (all P<0.05). Conclusion Taxol and suramin can maintain effectively functional blebs after trabeculectomy in rabbit. The efficacy of both 0.4 mg/ml taxol and 0.4 mg/ml suramin is better than that of 0.3mg/ml MMC, and the efficacy of suramin is the best.
